Can I tell you something?

I dislike planning.

Whenever I plan, things don't go accordingly.
Plus, with the whole concept of planning,
I immediately force myself to expect
an outcome. And as many of you know,
expectations, if don't met, can hurt.
Does this phrase sound familiar:

"Never expect anything in return".

But why are we so afraid of getting hurt?

As far as me goes, I am not afraid of getting hurt and experiencing
disappointment because disappointment (if handled correctly, with a positive view) can help an individual grow.
It can make a human become down-to-earth because it constantly remind us that all of us are humans and thus are perfectly imperfect.

Then why is it that I dislike planning?
